[Abstract]:High-speed permanent magnet generator has been widely used in aerospace and other fields because of its advantages of high speed and small volume. At present, the existing research on the basic theory of high-speed permanent magnet generator electromagnetic design is not perfect. Based on this, the structural design of high speed permanent magnet generator, the calculation method of magnetic field distribution, loss and temperature rise of high speed permanent magnet generator are studied in this paper. According to the characteristics of high speed permanent magnet generator with small scale and high speed, the design scheme of stator and rotor structure of generator is put forward, and the initial dimension design of high speed generator for micro turbojet engine is carried out. Based on the slip boundary method, the finite element model of magnetic field calculation for high speed permanent magnet generator is established, and the influence law of different rotational speed and different motor structure parameters on the electromagnetic performance of high speed permanent magnet generator is analyzed. Based on the calculation of magnetic field, the distribution of iron loss of stator is calculated according to the calculation model of iron loss, and the size and distribution of iron loss under different core materials, different stator structure and different rotational speed are studied. At the same time, the rotor eddy current loss, wind resistance loss and winding loss caused by high speed operation are calculated. Finally, the temperature field of the motor is analyzed with the loss components as the heat source, and the variation law of the motor temperature rise under different rotational speeds is analyzed. A generator system for turbojet engine with rated power of 400W and working speed of generator 80000~100000r/min is designed and implemented. The test platform of high-speed generator is set up and the related experimental research on electromagnetic performance parameters of high-speed generator body is carried out.
